I can believe that, but I also have to take those claims with a grain of salt.

Aside from Taleb, I don't recognize any of the people who claim Fridman blocked them, so for all I know, they tweeted obnoxious stuff at him and then complained about being blocked. Taleb is extremely abrasive, so I can't fault anyone for blocking him.

If it was like Yann LeCun and Andrej Karpathy complaining that Lex blocked them, then I'd question how aggressively Fridman blocks people, but if it's random Twitter accounts that seem to just shitpost all day, why do they have a right to communicate with Fridman?
